' 6 Claims. (01. 221-i-'-120) The present invention relates to machinesfor sowing and distributing commercial fertilizer such as lime and thelike.

An important object of my invention is to provide improved means foragitating the fertilizer and to provide improved feeding devices adaptedto cooperate therewith.

Another very important object of the invention resides in 'theprovisionof a machine of this nature which is exceedingly simple in itsconstruction, strong and durable, inexpensive to manufacture,adjustable, thoroughly effrcient and reliable in use and operation, andotherwise well adapted to the purpose for which it is designed.

With the above and numerous .other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction -and in the combination and arrangement of parts as willbe, hereinafter more fully described and claimed. 7

Figure '9 is a fragmentary bottom plan view showing the tooth bars andthe operating means therefor. v t

Referring to the drawings in detail, it will be seen-that the letter Hdenotes generally a hopper comprising sides 5, a rear wall 6', a frontwall I, and a bottom including inclined portions 8 and 9, the formerportion being more inclined than the latter portion. This hopper ismounted on a frame ill to rise therefrom. It will be noted that thewalls 6 and 1 diverge downwardly from each other. The back wall 6 isprovided with an opening H at the bottom end thereof. A plate I2 ismounted on the inside of the bottom end of the wall 6 to extendpartially across the opening II and is adjustable by means of bolts [4engaged in the wall 6 and extending through vertical slots in the plate[2. A bracket [5 is mounted across the top of the hopper I-I between thewalls 6 and I and has a bearing in the center thereof as at H. 'A crankshaft I8 has its ends journalled in openings It in the upper portions ofthe side waus 5 and its central portion journal'led in the bearing 11.On the crank shaft. iii are rods having their upper ends formed withsleeves 2| rockable the throws of the crank shaft. These rods to dependdownwardly and terminate in curved ends 22 which when at their lowermostposition are disposed adjacent the juncture of the bottom portion a withportion 9 as clearly m illustrated in Figure 4.

A- shaft' 25' is disposed across the frame ln in bearings 26 and has achain'and sprocket connection 27', with the'cran'k shaftlfl. A bevelgear 2"! is mounted on the shaft and mesheswith a tevei pinion isonasnaft 29 journaiied in bearing bracket 30. Shaft 29 has auniversalcoupling connection 3 I with the shaft 32 journalle'd in a bearing,brackt33. A disk 34 is mounted on the rear end of the shaft 32 and hasan eccentric pin 35 on which is rookable one end of a con- A nesting rod36. A pair of bracket plates 3'l'are mounted the frame It to the rear'ofthe hopper and have oblong longitudinalioo sss through. wliich is'slidable a bar 39 with teeth 40 projectin forwardly therefrom andextending" through the opening fl and partially along the lower part ofthe hopper bottom portion 9 and under the free1y' as isp er mitted bythe adjustmentof the 'plate lz 'andor the teeth {lGvvhich are simul- 40'ta eoosiy m ved 'actf'ossthe bottom of the hopper so astoproper1y"andeven1 dispense the fertilizer from the hopper in a manner toprevent clogging of the opening and to distribute the fertilizer evenlyover the ground.

It isthought that the construction, operation; utility and advantages ofthis invention will now be quite apparent to those skilled in this artwithout a more detailed description thereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, in thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

l. A material dispensing device comprising a frame, a hopper on theframe having a bottom slanting downwardly toward the rear of the hopper,a discharge opening provided at the bottom of the rear wall of thehopper, a crank shaft in the upper part of the hopper having throws, aswingable depending agitator bar secured by'its upper end on each one ofthe throws of the crank shaft,

the lower end of said bars being arranged to assume positions close tothe bottom of the hopper when the throws are in low position with thebars substantially perpendicular so as to-loosen material on thebottomandpush it toward the discharge opening, said bottom havinga'portion of greater inclination which the lower ends of said bars areadapted to touch as they move toward their said low position;

12. A material dispensing device comprising a frame, a hopper on theframe having a slanted bottom slanting downwardly toward the rear of thehopper said bottom having a forward portion of greater inclination, adischarge opening at the bottom of the rear wall of the hopper, a crankshaft in the upper part .of the hopper, swingable dependingagitato'rfbars secured by their upper erid onthethrow of the crankshaft, the low'er'end of the bars being arranged to assume positionsclose to the juncture of the lower end of theportion'of greater.inclination and the bottom of the hopper when the throw is in lowposition so as to scrape material from the portion of greaterinclination and loosen material on the bottom and push it toward thedischarge opening,

ar'id a transversely-reciprocable series of teeth on .the frame and.extended into the opening in the rear wall f-of the hopper for scrapingthe bottom "and facilitating'idischarge of material from the hopper,said crank shaft and reciprocable series ofteeth being connected forsimultaneous operation.

3. A materialsupport, a hopper on the support and having a dischargeopening in the lower end of its rear wall, a plate carried by the rearwall above said opening and adjustable vertically to restrict theopening, a plurality, of transversely reciprocable teeth carried bythe'support and extending into the hopper throughthe said opening andbelow said plate for scraping material on the bottom of thehopper anddistributing the material issuing from the hopper through said opening,agitator means in the hopper for scraping the bottom andmoving thematerial in the hopper to- .ward the opening, and meansoperativelycondispensing device comprising a' necting the agitator means and saidplurality of reciprocable teeth for simultaneous operation.

4. A material dispensing device comprising a support, a hopper on thesupport comprising downwardly diverging front and back walls, the backwall being provided at its lower end with a transverse opening,adjustable closure means on the back wall for restricting the opening,the front wall having a lowerportion inclined toward the back wall, thebottom of the hopper rising from the back wall to join the lower end ofthe said lower portion, a crank shaft journaled in the upper part of thehopper, a plurality of depending bars rockably mounted by their upperends on the throw of the crank shaft, the lower ends of said bars beingarranged to scrape the said lower portion and a part of the bottom asthey move up and down and throw material in the hopper toward the saidopening, a transversely reciprocable member supported on the support and7 having a plurality of teeth arranged through the said opening and inscraping relation to material on the hopper bottom and toward and awayfrom which the closure means is adjustable, and means "operativelyconnecting the crank shaft and the reciprocable member for simultaneousoperation terial from said hopper through said opening, and

means within said hopper operable to scrape an-' other portion of saidbottom and urge material in said hopper toward the first mentionedportion connected to the front wall of said hopper, and

depending agitators arranged in the hopper to move up and down and toswing so as to engage their lower ends with and scrape said secondportion of said bottom, the lower ends of said agitators being curvedtoward the back wall of the hopper, so :as toshovel material in thehopper along said first portion of the bottom toward said 50 opening,and means operating said agitators.
